FRANKLIN, Tenn.--(BUSINESS WIRE)--Acadia Healthcare Company, Inc. (“Acadia” or the “Company”) (NASDAQ:
ACHC) today announced the sale of additional shares of common stock
pursuant to the underwriters’ exercise in full of their option to
purchase additional shares related to the Company’s previously announced
registered public offering of 10,576,623 shares that closed December 12,

additional 1,050,000 shares of common stock from the Company and an
additional 533,153 shares of common stock from certain of the selling
